Shift + wheel and Ctrl + wheel doesn't work anymore in Blender 2.8?
I solved the problem manually add key map item in the preferences.
User preferences - Input - 3D View - 3D View Global - Add new - in field &quot;Identifier operator to call on input event&quot; type view3d.view_pan - then choose your key and action Pan left or right \ up or down.
This is not solved by Import key configuration from blender 2.79.

On Blender 2.83.4:

Click Edit &gt; Preferences.
Click the Keymap tab.
Expand 3D View.
Expand 3D View (Global).
Scroll to Pan View Direction.

At this point, you can change the options to suit your preferences.
